Kelly said he expects the financial effects of the accident to finally fade.
"I think our business stays well," he said.
Southwest reported a first-quarter profit of $ 463 million on Thursday, a 37 percent increase from a year ago. He said his income outlook was cushioned by a competitive pricing environment and a suboptimal flight schedule triggered by a temporary drop in the size of his fleet.
That contraction, due to a wave of retirements for older planes in 2017, has forced the carrier to stretch its fleet by scheduling flights in the early morning and later in the evening, times that are less popular with travelers and less profitable for the airline.
Fuel prices rose
American also reported gains Thursday, with a first-quarter profit of $ 186 million, up 45 percent from the previous year because fuel prices increase the airline's expenses .
The Fort Worth-based airline said its fuel costs were up 25.7 percent, increasing its expenses by $ 412 million compared to the previous year.
"Excluding the increase in the price of fuel, everything else feels pretty good on American," general manager Doug Parker said during a phone call with analysts on Thursday.
Parker's help with the rapid increase in fuel prices is pushing costs for now, but in the long run he expects the industry to adapt, even through higher rates.
"As the cost of production increases, the price of the trip should rise in some way," he said.
